“The clashes show there is clearly a great deal of polarisation and mistrust. This can only be overcome if all sides commit to a political process, defined and agreed by Egyptians themselves, that leads to deep and sustainable democracy,” the statement added.

“During my visit last week, I saw some potential for this to happen. The European Union will continue to support the Egyptian people in this process," Ashton added.

Ashton’s visit to Cairo was an effort to encourage dialogue between Egyptian authorities and the Muslim Brotherhood.
